Installation
1. Remove the back panel of the sensor with a small screwdriver.
2. Install the battery. The EMS requires one AA battery. The battery type is
3.6V Lithium Battery (ER14505).
Caution: Using batteries other than the ones provided may result in loss of performance and
battery life, and also damage to the device. Dispose of properly, observing environmental
protection rules.
3. Mount the back panel on the surface using the adhesive tape.
4. Attach the cover to the back panel.

Door activity sensor
Make sure that the magnet part is mounted on the “door” (the part that is going to
open) and the sensor part is mounted on the frame. For double doors, put one part on
each door.
The distance between magnet and sensor should, if possible, not exceed 10mm. Make
sure that the magnet and reed switch are mounted next to each other. Detection range
will be affected by the materials of the door and frame, different materials result in
different ranges. The reed switch is on the end of the sensor
without
the stripe. The
magnet needs to face this side of the sensor (see image).
Water leak sensor
Make sure that the back panel is mounted on the surface where the water may leak. The
sensor element that detects the leak is placed on the back panel. For example, if EMS is
going to monitor water leak from a dishwasher, place the back panel onto the floor
under the machine.
Temperature/humidity sensor
Place the device in an open space on a wall, under a desk or on any other flat surface.
Make sure that the sensor is not faced by direct sunlight or placed near air vents or
other places where it may measure values that is not representative for the rest of the
room.

Sensor configuration
All sensor settings can be configured via a smartphone application with NFC
(Near Field Communication) or over the air via the network server and downlink
data to the sensor. The sampling rate, spreading factor, encryption keys, port,
and modes can be changed. All sensor settings can be locked from the server or
NFC to make end-users unable to read or change settings on the sensor.
NFC Configuration
1. Download ELSYS “Sensor Settings” application from Google Play and install
it on a smartphone or tablet. The device must support NFC.
2. Enable NFC on the device and start the application.
3. Place your device on top of the EMS sensor to connect with the NFC
antenna.
You may need to remove the top cover and battery to get connection.
4. Remove the device. Current settings will be displayed in the application.
5. Use the application to change any settings if needed.
6. Quickly tap the device on top of the EMS to give the new settings to the
sensor. Make sure that the application confirms your new settings.
7. Wait for the sensor to reboot (5 sec), indicated by the LED flashing. Sensor
settings have been updated.
See the section “Help” in the application for more information.
Over the air configuration
All settings may be configured over the air via your LoRaWAN® infrastructure.
Please visit the support section on our webpage for more information regarding
downlink protocol.
Application parameters
All parameters for the “Sensor settings” application can be found in our settings
document. Please visit the support section on our webpage for more information.

Sensor behavior
NFC Read / Write
1. When reading or writing NFC
configuration data to the sensor, it starts
a timer and delays its action 5 seconds.
2. After the delay, the sensor determines if
the NFC data has changed or not. If the
data has changed, the sensor reboots
and starts from power-up.
3. Write your settings in the application
and then locate the NFC antenna of the
phone and sensor. Keep the two
devices close and don’t move them to
get the best connectivity as possible
when writing or reading data to the
sensor. Bad connection can be caused
by long distance, wrong location, or
rapid movement.
4. When you have written data to the sensor, let the sensor reboot and restart
before trying to write again.
You should always validate your settings by reading the NFC data after the
sensor has restarted.

Elektroniksystem i Umeå AB Industrivägen 12, 90130 Umeå, Sweden

Sensor startup
1. When the sensor starts up, it loads
configuration from the internal memory and
merges it with user configuration.
2. When the configuration is done, the sensor
writes the new settings to the NFC chip. The
sensor always writes new configurations to the
NFC chip when something changes in the
sensor or if NFC data is corrupted by an NFC
writer or phone. The sensor always writes the
new configuration to NFC chip at startup.
3. When the configuration is done, the sensor
tries to join the network if OTAA (Over the Air
Activation) is enabled.
4. The sensor LED flashes orange when it tries to
join a network. It will try to join every 10
seconds initially. This interval will increase to
save battery, at most up to one time per hour.
5. After successful connection to a network, the
sensor sends a settings packet and enters
sampling mode.

Sampling mode / Periodic
measurement
The sensor makes periodic
measurements according to the user
configurations.
Opening activity (Reed switch)
When the reed switch changes state from
closed to open, the activity is added to a
pulse counter that keeps track of the
number of opening events. The number
of the pulse counter and the current
state is added to the data packet.
If the state is changed from closed to
open, the pulse counter remains
unchanged and only the state and
current number of counts is added to the
data packet.
After values has been added to the
packet, the EMS schedules a
transmission.

Schedule Transmission
The sensor transmits the data
according to the user
configurations.
Note: The configured sending interval can
be overridden by network limitations. Due
to this, the spreading factor and sending
interval settings might result in longer
intervals than intended.
Water leak detector
The EMS has probes mounted through the back panel which are constantly
monitored by the sensor. The sensor can be configured to send alarm
immediately when water is detected. Detection is sent periodically. Value is 0 for
dry conditions and 1 when water is detected.
